VODACOM PLAYING HIDE AND SEEK WHEN IT COMES TO CANELLATIONS.

I have sent through my intention to cancel my contract on the router I have. I have sent this through to the SMS no *** more than 10 x with NO RESPONSE. I receive a message to say until such time that I receive an email with notification that it has been cancelled, it is not cancelled.

I keep receiving calls to upgrade my contract, but no one is interested when I say I am cancelling my contract????

You cannot speak to a consultant, so where to from here????
